Linux Shell脚本之GitLab远程备份

注:Gitlab是一个Git服务程序,有Web图形界面和一系列管理工具,具体详细介绍可以Google it。

这一篇可以说是《Linux Shell脚本之Atlassian confluence远程备份方法》的姊妹篇。其说明和原理是和上一篇是一样的,其核心原理都是core dump、scp、ssh和find+rm,但也有不同。

1.Gitlab本身提供了较好的备份方法,只是一个命令那么简单,并且它也支持远程备份(远程存储和云存储),例如它可以存储到aws的s3上。

2.本脚本运行在Gitlab服务器上,不在备机上,上一篇的脚本是与运行在备机上。

脚本如下:

#!/bin/bash
# This shell script will execute on A Server
 
# SHELL=/bin/bash
# PATH=/sbin:/bin:/usr/sbin:/usr/bin
# MAILTO=root
# HOME=/
# For details see man 4 crontabs
# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name command to be executed
# m h  dom mon dow  command
# execute on 11:59 per sunday
# 59 11 * * */0 $0 >/tmp/gitlab_backup_$(date -d "yesterday" +"%Y%m%d%H%M%S").log
# execute on 23:59 per day
